Ships and Shipping [PDF]

open access: yesNature, 1905
A VERY excellent little volume and a most handy addition to any shipping office. The naval information makes it also a very useful book to naval officers. One slight improvement would be useful—port-to-port distances round the coast of Great Britain and Europe; for example, London to Plymouth. Ships and Shipping. By Commander R. Dowling. With a preface
